NAME
       POE::Filter::Zlib - A POE filter wrapped around Compress::Zlib

SYNOPSIS
	   use POE::Filter::Zlib;

	   my $filter = POE::Filter::Zlib->new();
	   my $scalar = 'Blah Blah Blah';
	   my $compressed_array	  = $filter->put( [ $scalar ] );
	   my $uncompressed_array = $filter->get( $compressed_array );

	   use POE qw(Filter::Stackable Filter::Line Filter::Zlib);

	   my ($filter) = POE::Filter::Stackable->new();
	   $filter->push( POE::Filter::Zlib->new(),
			  POE::Filter::Line->new( InputRegexp => '\015?\012', OutputLiteral => "\015\012" ),

DESCRIPTION
       POE::Filter::Zlib provides a POE filter for performing
       compression/uncompression using Compress::Zlib. It is suitable for use
       with POE::Filter::Stackable.

       This filter is not ideal for streaming compressed data over sockets
       etc. as it employs compress and uncompress zlib functions.

       POE::Filter::Zlib::Stream is recommended for that type of activity.

CONSTRUCTOR
       "new"
	   Creates a new POE::Filter::Zlib object. Takes one optional
	   argument,

	     'level': the level of compression to employ.

	   Consult Compress::Zlib for details.

METHODS
       "get"
       "get_one_start"
       "get_one"
	   Takes an arrayref which is contains lines of compressed input.
	   Returns an arrayref of uncompressed lines.

       "get_pending"
	   Returns any data in a filter's input buffer. The filter's input
	   buffer is not cleared, however.

       "put"
	   Takes an arrayref containing lines of uncompressed output, returns
	   an arrayref of compressed lines.

       "clone"
	   Makes a copy of the filter, and clears the copy's buffer.

       "level"
	   Sets the level of compression employed to the given value. If no
	   value is supplied, returns the current level setting.
